Type the value in the box next to Mpa (using the drop down to change the unit of measurement). Yield strength differs in that the bolt or test coupon is pulled to failure, and the yield is calculated (using the 0.2% offset method) along with the tensile, elongation and reduction of area. To calculate the modulus of elasticity E of material, follow these steps:. In ACI318-14 clause 17.2.3.4.3 there is term: NOMINAL STEEL STRENGTH of anchor, I was wondering is this same as Yield Strength you defined above? However, the limiting factor will be the material it is screwed into, and the wood will typically yield before the lag bolt will, so you may have a problem using only one lag bolt. @E- Most mass produced items like that are made from low carbon steel wire. @Ahmed- You would need to consult an engineer familiar with the project in order to determine that.
